How to Adjust Brightness Manually on a Laptop or Tablet

#Computer app to lower screen brightness windows

Windows can change it based on whether you're plugged in, based on how much battery power you have left, or using an ambient light sensor built into many modern devices.

When you're in a dark room, you'll want it dim so it doesn't hurt your eyes. Decreasing your screen brightness will also help you save power and increase your laptop's battery life.Īside from manually changing the screen brightness, you can have Windows change it automatically in a variety of ways. When it's bright outside, you want to turn it up so you can see. The application's interface can be set to non-dimmable, this is possible because it uses an overlay and the option is handy if you've set the brightness too low and can't see the slider.You probably need to change your screen brightness regularly. If you hit the X in the window's title bar, it closes the program instead of minimizing it. You may toggle the option to start the program minimized instead of the window being displayed. The Options tab lets you set Dimmer to auto run when Windows boots. This issue was random and only happened once or twice. Exiting the program and restarting it fixed the issue. The most annoying bug I ran into with Dimmer, was when a third of my monitor's screen was set to a different brightness level, it was covered by the overlay while the rest of the screen wasn't. As a workaround, delete the JSON settings file that the program creates, when you switch display modes to make it work correctly. Dragging one of the sliders affected the brightness of both screens. Sometimes it displayed two sliders when the screens were in 'duplicate' mode. This way, when you adjust the slider, only the screen that has a checkbox enabled will be dimmed.ĭimmer is in beta and it shows, occasionally it tends to bug out. There is a check box above each screen's slider, toggle the box to disable Dimmer for the corresponding screen. If you've enabled 'extend' mode' you'll be able to control the brightness of each screen individually. If you've a dual-monitor setup and are using the second monitor to duplicate the primary display, only one slider is displayed and adjusting it modifies the brightness of both screens at the same time. There are a few things that you need to keep in mind while using the program. Here's what my screens look like normally (max brightness)Īnd here is the lower brightness version, courtesy Dimmer (on the laptop)ĭimmer can be used with single monitors, as well as dual or multi-monitor setups, though it is intended to be more useful for the latter. Be careful while dimming the display, I could barely see anything at the minimum level. Remember, 0 is maximum brightness while the minimum is 90. The box below the slider indicates the brightness level of the slider. You'd expect it to be the other way around, and quite frankly, I would have preferred a horizontal slider to this. Drag it upwards to reduce the brightness, or drag it down to increase the brightness. Speaking of which, the slider is a bit odd. Every screen has a number assigned to it, and has its own slider.

The 'screens' tab displays each monitor (including the laptop screen), connected to the computer. It also opens a small window that has 4 tabs. Run it and it places an icon on the system tray.

The portable software's executable is about 90KB. If your screen's brightness had really been modified, a screenshot will not show such a difference. Take a screenshot while running Dimmer, it will include the 'dull look' of the overlay. Programs like F.lux or Lightbulb do the same. But it does help reduce eye strain, which is sort of the point anyway. Imagine how your monitor would look like if you're wearing sunglasses, it's like that. Dimmer is a freeware tool that solves this problem in a subtle way.ĭimmer does not reduce the actual brightness of the screen, instead it adds a virtual overlay on top of it. Trying to do something as simple as adjusting the monitor's brightness shouldn't require you to fiddle with a clunky menu.
